Crunchbase MCP Server

Instructions

Implementation Reference

• src/index.ts:371-388 (handler)

  MCP tool handler for 'get_acquisitions': validates input arguments, constructs params, calls crunchbaseApi.getAcquisitions, and returns JSON stringified response.

  case 'get_acquisitions': {
    if (!args || typeof args !== 'object') {
      throw new McpError(ErrorCode.InvalidParams, 'Invalid parameters');
    }
    const params: GetAcquisitionsInput = {
      company_name_or_id: typeof args.company_name_or_id === 'string' ? args.company_name_or_id : undefined,
      limit: typeof args.limit === 'number' ? args.limit : undefined
    };
    const acquisitions = await this.crunchbaseApi.getAcquisitions(params);
    return {
      content: [
        {
          type: 'text',
          text: JSON.stringify(acquisitions, null, 2),
        },
      ],
    };
  }

• src/crunchbase-api.ts:128-157 (handler)

  Core implementation of getAcquisitions: resolves company UUID if needed, builds search query for acquisitions where the company is acquirer or acquiree, calls Crunchbase API /searches/acquisitions, returns results.

  async getAcquisitions(params: GetAcquisitionsInput): Promise<Acquisition[]> {
    try {
      let companyId: string | undefined;
  
      if (params.company_name_or_id) {
        // Get the company UUID
        const company = await this.getCompanyDetails({ name_or_id: params.company_name_or_id });
        companyId = company.uuid;
      }
  
      // Build the query
      let query = '';
      if (companyId) {
        query = `acquirer_identifier.uuid:${companyId} OR acquiree_identifier.uuid:${companyId}`;
      }
  
      // Get the acquisitions
      const response = await this.client.get<CrunchbaseApiResponse<Acquisition[]>>('/searches/acquisitions', {
        params: {
          query,
          limit: params.limit || 10,
          order: 'announced_on DESC'
        }
      });
  
      return response.data.data;
    } catch (error) {
      console.error('Error getting acquisitions:', error);
      throw this.handleError(error);
    }

• src/index.ts:261-277 (registration)

  Tool registration in ListTools response: defines name 'get_acquisitions', description, and inputSchema.

  {
    name: 'get_acquisitions',
    description: 'Get acquisitions made by or of a specific company',
    inputSchema: {
      type: 'object',
      properties: {
        company_name_or_id: {
          type: 'string',
          description: 'Company name or UUID',
        },
        limit: {
          type: 'number',
          description: 'Maximum number of results to return (default: 10)',
        },
      },
    },
  },

• src/types.ts:134-137 (schema)

    company_name_or_id?: string;
    limit?: number;
